A metasedimentary source of gold in Archean orogenic gold deposits

Geology, 2021
AbstractThe sources of metals enriched in Archean orogenic gold deposits have long been debated. Metasedimentary rocks, which are generally accepted as the main metal source in Phanerozoic deposits, are less abundant in Archean greenstone belts and commonly discounted as a viable metal source for Archean deposits.

Aseismic Refinement of Orogenic Gold Systems

Economic Geology, 2020
Abstract Orogenic Au deposits have contributed the majority of Au recovered globally throughout history. However, the mechanism that concentrates Au to extremely high bonanza grades in small domains within these deposits remains enigmatic.

Coeval emplacement and orogen-parallel transport of gold in oblique convergent orogens

Tectonophysics, 2016
Abstract Varying amounts of gold mineralisation is occurring in all young and active collisional mountain belts. Concurrently, these syn-orogenic hydrothermal deposits are being eroded and transported to form placer deposits. Local extension occurs in convergent orogens, especially oblique orogens, and facilitates emplacement of syn-orogenic gold ...

Tectonic-Diffusion Estimate of Orogenic Gold Resources

Economic Geology, 2010
Age-frequency data are used to determine amounts of vertical tectonic displacement experienced by the global population of orogenic gold deposits following their emplacement at a crustal depth of 10 ± 1 km. Knowledge of this tectonic dispersion allows for an estimate of the total crustal endowment of gold in orogenic gold deposits.
